Is DWT usable?

[dangbinghoo]

I have noticed DWT moved to as a dub package. And said it easy to 
startup.

So, I just cloned the DWT git repo. And did the same thing as 
README.

But I got the following :

```
dub --single main.d
Performing "debug" build using /usr/bin/dmd for x86_64.
dwt:base 1.0.1+swt-3.4.1.commit.2.gd729d7d: target for 
configuration "library" is up to date.
dwt 1.0.1+swt-3.4.1.commit.2.gd729d7d: target for configuration 
"linux-gtk" is up to date.
main ~master: building configuration "application"...
Linking...
To force a rebuild of up-to-date targets, run again with --force.
Running ./main
Program exited with code -11
```

the same result as I tried half year ago.
